Borussia Dortmund star Shinji Kagawa could miss the rest of the season after he was injured in Japan's Asian Cup semi-final win over South Korea on Tuesday.

Kagawa has been one of the stars of the Bundesliga this year with eight goals in 17 league appearances and has also impressed in Qatar for his country - netting a brace in their 3-2 quarter-final win against the hosts.

However, he sustained a broken metatarsal while helping the Blue Samurai to the final and could now be a big miss for club and country.

"Shinji has sustained a metatarsal fracture and is already on his way back to Germany to undergo further treatment,'' Bernhard Schmittenbecher, the player's agent, was quoted as saying by Bild. ''He could be sidelined for the remainder of the season."
